I'm not positive, but I think it is like the 36 and you have to remove all your body bolts and lift the body enough to push one side up high enough to allow the other side to drop. You will have to get your filler neck off and that can be a bear!! The bolts that hold the tank on must be removed from underneath the frame ledge and if the tank has never been removed, start squirting a top grade nut buster (penetrating oil) several days before trying to get them loose. You can not get to the nuts to hold them and they are actually cage nuts and will spin in the cage before the bolt will wring. If it does, cut the head off and rework when you get the tank removed. Good luck!!!

Yes, there are 3 bolts holding the tank to the frame. You should not have to remove body bolts, etc. to get any early Ford(32-48)tank out. The filler neck mounts into the tank by different methods through the years. The appropriate Ford Service Bulletins ( available new and now) should hav ethe process described or illustrated. Your book will be the 37-40 Bulletins. Any early Ford parts dealer sells these books.

Pasadena, I really respect you West Coast boys and you hotrodding leading edge, but having owned a 36 Ford coupe since 1960 and a 36 PU since 1974, built many others, and have a dogeared service bulletin book, I don't think I would pull the bed/raise the body to get the tank out if I did not have too. If someone knows a way of doing it, I sure would like to learn since I'm getting long in tooth and don't enjoy the heavy lifting as much!!

The only possible reason you would have to remove body bolts is if the body mount blocks(rubber) have completely deteriorated to nothing or were not installed when the car was rebuilt (body off). This is not a built-in "Better Idea", it's a matter of a car lasting over 65 years when it was actually made to last 10 or 15.

Thanks, for the responces. I think my leak is where the filler pipe goes into the tank. What I can see of it, it looks like it is threaded into the tank. Does anyone know how it is connected to the tank on a 37 coupe, or is there different ways? I ordered the service bulletins to see if I can get any info from them.

Yes, the filler neck is flanged and the flange nut requires a special spanner wrench to turn it. Since it is about 2" diameter, it takes a lot of ft lbs to move. You have a fighting chance if you are brave enough to fill the tank with water or some inert gas so you can put some heat to it, then you can bust it loose. I have one that leaks and can't budge the flange nut, so I have successfully stoped the leak with jet fuel cell sealant that is past shelf life. If you have some buds that are jet mechanics, they could get you some or you might check with your local military surplus outlets.
